T9 all whom'it concern:

Be known .that'I, WILLIAM J.'KEH0E, a citizen of the United States,residing at Washington, District of Columbia, have invented new and useful Improvements in Stenographic Machines, of which the following is aclear and exact specification. I

My improvements consist in a stenographic machine, of two: distinctsetsof keys and markers, five in each set, and the machine is so designed asto make impressions across a paper ribbon parallel groups and sjrlla.

" bles; and the objectof my improvements are, first, to

be able to write complete ntences without theaid of a spacer; second, toafford;facilities fori'depressing the two distinct sets of markerssimultaneously-Maltanately. I attain these objects b' y the mechanismillus--' trated in the accompanying dra v Figure 1 is aperspectiv'ewiewe machine, Fig. 2

' is a view illustrating principally the comparative distances betweentheteeth-onthe ratchet-wheel and the distance between the two sets-ofmarkers. Ih'g. 3

" shows a result obtained by this machine. 4 shows another result. Fig.5 shows the resultobtained by the present method of stenoggaphic machinein which there are sixtyseven depressions as compared 'to twenty-sixdepressions of 4, my machine;

Similar reference characters'denote the same parts throughout theseveraldrawings."

.1, designates the base 'of the machine to which details maybe fastenedbifurcated posts orsstaildards,

2, form fulcrums for the finger keys. Thekeys consist of flattened rods,3, with finger-pieces, 4. It ,will be noticed by referring to thedrawings that there are -tw0 independent sets of.keys and markers, 'A,and B, respectively, five in each set. The keys, A, prxisess dashes fortheir marking characters and the keys, B, possess dots; so if the tenkeys be depressed the result produced would be read across the paperribbon, five dashes and five dots, the dashes appearing first and thenthe dots, but parallel and close to each other, and

by repeating this operation several times I accomplish theresnlt asshownin Fig. 3.

Springs, 5, serve to keep the rear end of the-marking keys in a lowesmost position; they are fastened through holes in the flat plate, 6.This plate supports two bifurcatedg'iosts, 7, to which is pivoted aspace-actuating device, 8. Said device is drawn down by an adjustablespring, 9, whose lower end is attached to the base of the machine atanydesired point. This spacing device over-lies the marking keys near theinner end, so that it is lifted by any of the said keys as they areoperated upon The inner end of the spacing device car Specification ofLetters Patent.

! depression of the marking keys. At each stroke of any one or more ofthe marking keys, the spacing device is raised such a distance as tomove the pawl, 10, one

descends and the spacing device with it, the rubber roller, 12, turnsand pulls the paper ribbon such a distance'as to print impressions onsaid paper ribbon as illustrated in 4.

i It will be observ'edthat by the use of this instrument the spacingdevice, 8, causes 'no marking effect upon thepaper ribbonand is'only forthe purpose of disti l guishing entirely new paragraphs, punctuation,etc. Further, it must be understood that it is 'not essential to makeuse of. the spacing device between words as is now practiced; w

Referring to the drawings it will be noticed that an inked ribbon, 13,at each movement of either the spacing device'or marking keys movesslowly along'underneaththe rubber impression-roller, 12. This rubberroller has secured to its rear end an intermediate spurgear, 14, whichmeshes either one of the larger spurgears, 15, and 16, respectively.-When the inked rib- .boniswound all on one reel, 17, its direction isreversed, which is accomplish ed by throwing the intermediate gear, 14,to the right," (or left, as the case may be) to the reel,.18. The paperribbon is supplied from a paper 011, '19. a

On one side of. the machine is a guide, 20, which leads the paper ribbonbetween a friction-roller, 21, and the impression-roller, 12. The guideand frictionroller may be supported from the base of the machine asshown in Fig. 1.

- The chief advantage of my improvements is, that by means of them thespeed of the stenoglaphic machine is increased considerably over onehundred per cent.

I am aware that. prior to my invention stenographic therefore do notclaim such a combination broadlyf but, v
